Patent GB-2072668-A (GB)
Title: Process for reducing the water content of alcohol-water mixtures
IPC: C07C31/00
Filed: 1981-03-19
Abstract: An improved process is disclosed for producing petrol-grade C2-C4 alcohols from aqueous mixtures which contain these alcohols. The improvement is that the aqueous mixture is reacted with a tertiary olefin in the presence of a catalyst having an acidic character, preferably at a temperature of from 40 to 90 DEG C and at a space velocity of from 5 to 25 litres of reactants per litre of catalyst per hour. Preferred catalysts are acidic ion-exchange resins, especially those having -SO3H groups. The temperature and space velocity ranges are critical in order to minimize the parasitic ether- forming reaction.

Title: Feedscrew device
IPC: B23Q5/40
Filed: 1981-04-02
Abstract: A feedscrew device comprises a movable member (29) which is slidably supported by a guide member (16) and is moved by a nut member (23) threaded onto a feedscrew 14. The nut member is connected to the movable member by means of a connecting member (34) capable of accommodating a dimension variation in the radial direction of the feedscrew and tiltable with respect to a direction perpendicularly intersecting the axis of the feedscrew. Complicated movements of the nut member due to a sweep of the feedscrew, eccentricities of bearings and the like can thus be accommodated, without affecting smooth movement of the movable member. <IMAGE>

Title: Method and an arrangement for storing organic fibrous material in a stack
IPC: F26B21/10
Filed: 1979-05-15
Abstract: Method of storing organic fibrous material in a stack (1). To increase, in an energy-technical optimal way, the heat content of the material, air is blown into the stack (1) at a number of different levels depending on the height of the stack and at each level, at a number of points evenly distributed over the cross-section of the stack. At said levels and at a distance from the air blowing-in points air is sucked out of the stack. The temperature of the sucked-out air at mainly each suction point is made to control the blowing-in of air at the adjoining blowing-in points so that the temperature of the fibrous material is kept within a predetermined temperature range. The water and heat contained in the sucked-out air is collected and at least some of the air thus dried and cooled is used for blowing into the stack (1).

Title: Brass-coated metal objects for reinforcing rubber articles
IPC: C08J5/04
Filed: 1981-05-27
Abstract: Brass-coated metal objects covered with cobalt, more particularly steel wires covered with brass and with a thin layer of cobalt, have a high gradient of cobalt concentration on the surface to a depth of 500 A DEG  and are obtained by depositing from 0.05 to 5% by weight of cobalt, relative to the brass, on a brass-coated wire, and then wiredrawing, the pressure and the heat involved in the wiredrawing, which is carried out simultaneously or separately, ensuring a good interpenetration of the cobalt with the brass, which leads to a good cohesion of the whole metal coating. The metal objects thus obtained are useful, e.g., for reinforcing tyres straps, pipes and conveyor belts.

Inventor: DUHL DAVID NOEL
IPC: C22C19/05
Filed: 1982-09-07
Abstract: The additions of minor amounts of hafnium and silicon and mixtures thereof to nickel base superalloy single crystal articles provide significantly improved oxidation resistance. The oxidation resistance is improved both for the case of uncoated articles and in the case where a protective coating such as for example, a MCrAlY coating is present. For example the addition of 0.1% hafnium is observed to improve the oxidation resistance by a factor of 4 at 1149 DEG C and a similar addition improved the coated oxidation resistance by a factor of about 2.5 at 1177 DEG C.

Abstract: PCT No. PCT/GB82/00321 Sec. 371 Date Jul. 11, 1983 Sec. 102(e) Date Jul. 11, 1983 PCT Filed Nov. 10, 1982 PCT Pub. No. WO83/01714 PCT Pub. Date May 11, 1983.An amplifier which is particularly suitable for low supply voltage operation and which is relatively insensitive to power supply voltage variations includes a signal amplifying stage (11) and a control stage (10). The signal amplifying stage (11) includes the output load (13), such as a loudspeaker, in series with a transistor (12) which is controlled by a current mirror circuit (14, 15, 16) in the control stage. The circuit acts by continuously comparing part of the voltage across the output load (13) with a very low reference voltage arising from the difference in the base-emitter voltages of two transistors (14, 15) operating at unequal collector current values. This causes voltage excursion peaks appearing at the junction of the output load (13) and the amplifying transistor (12) to be clamped to a voltage equal to or otherwise related to that at the opposite side of the output load (13).

IPC: G11C7/20
Filed: 1981-12-21
Abstract: Arrangement to destroy by erasing the information contents in data memories and program memories included in a data base installation, without destroying the equipment. An operation device (MO) is brought to activate a first group of parallelly working address generators (AD1-ADn), these generators successively generating and selecting all addresses in a memory (DS1-DSn) which is separately connected to each of the generators and which is part of a first memory group. Gate circuits (GD1<u1>u-GDn<u4>u) are connected to the data inputs on each memory unit in this first memory group through which binary digits of the same logical level is written into the selected addresses of the memories irrespective of what is already written there. The operation device (MO) also activates a second group of parallelly working address generators (AP1-APn), these generators successively generating and selecting all addresses in a memory (PS1-PSn) which is separately connected to each of the generators, said memory being part of a second memory group. Gate circuits (GP<u1>u-GPn<u4>u) are connected to the data inputs of each memory unit in this second memory group through which circuits binary digits of the same logical level are written into the selected addresses of the memories. After completed erasing in said first and second memory group an activation signal is transmitted to a control device (L) which then indicates that the erasing is finished.

Title: Gas pressure regulator
Inventor: THOMPSON BARRY
IPC: G05D16/02
Filed: 1983-03-03
Abstract: A gas pressure regulator for supplying gas under pressure to a gas distribution network has a control valve 5 operated by an actuator 8 comprising a flexible diaphragm 7 urged in one direction to open the control valve by a spring 9. A feedback pipe 10 supplies gas from the downstream side of the control valve to the opposite side of the diaphragm to act against the spring and modify the operation of the control valve in accordance with downstream gas pressure. A restrictor arrangement 12 incorporated in the feedback pipe is also connected to the upstream side of the control valve and is designed to reduce the flow area through the feedback pipe automatically as the upstream pressure increases and thus prevent amplification of standing pressure waves formed in the gas distribution network. <IMAGE>
